Any /16 that has a lot of records can be split off into its own 2.10.in-addr.arpa. An if a /24 gets really busy, you can split it out 5.1.10.in-addr.arpa There is no need to create all 256 /16's or all the /24's, just create them as needed. If having different sizes is too confusing, I suggest all /16's. -- Bob Harold
